Abstract: Un systeme de sechage rotatif pour un materiau particulaire comprend une secheuse rotative (1) du type a cylindres multiples avec un axe de rotation horizontal. Un four (2) est monte a une extremite et un separateur centrifuge dispose horizontalement (7) du type a volute est monte a l'autre extremite. Un petit separateur a cyclone (12) est accouple au separateur a volute et il est connecte dans un systeme a circuit ferme au separateur a volute pour le recyclage permanent de l'air au travers de ce dernier. La dimension verticale de la secheuse rotative etant essentiellement la plus grande, le profil du systeme est reduit au minimum. La secheuse rotative est formee avec un cylindre interieur (17) conique ayant une entree relativement petite et un diametre de passage augmentant progressivement jusqu'a une grande extremite de refoulement accouplee a un passage intermediaire entre le cylindre interieur et un cylindre intermediaire de diametre constant (16). La section du passage intermediaire s'agrandit continuellement jusqu'a un passage de decharge finale forme par un cylindre externe concentrique (15). Des plaques d'usure remplacables (53) supportent une extremite des cylindres intermediaire et interieur pour limiter leur mouvement relatif. Les passages sont proportionnes pour etablir une distribution volumetrique de sechage et de fuite de temperature optimum pour empecher la degradation du produit et assurer un sechage efficace.

Abstract: A room-heating and air-conditioning device (11) consists of a storage device (15) for a fluid storage medium based on water, heat collectors (17) and coolers (22) arranged outside on the building, a window element (14) which also serves as heat collector, and radiators (16) and coolers (26) situated in the room (13). The entire device can be erected as a compact, largely preassembled unit and serve as an exterior wall element. One unit is provided per room. The storage device (15) has two superimposed regions (30, 31) which are thermally separated from one another by natural thermal layering and lateral constrictions (28), and a heat pump (39) arranged in the storage medium. The window element (14) contains absorption members (67) which can be different colours on the two sides and which are whirled up between two window panes (51) by the flow and thus, independently of the speed of flow, take on darkening and absorption properties. <IMAGE>

Abstract: The drawing shows part of the print head and associated drive circuitry of an ink jet printer. The head comprises a tubular piezo-electric transducer (11,12, 13b) driven from a periodic source 37 running at the resonant frequency of the piezoelectric cavity 17 or from a clock source 46 gated by print signals. During driving by source 37 the transducer is energized with a series of pulses for a preselected short time period (delay 39) and at a repetition rate substantially equal to a resonant frequency of the ink cavity (17). This effectively purges any entrapped air from the ink system. Except during purging, the transducer operates asynchronously in drop-on-demand mode in response to discrete binary print signals. 
     Purging is accomplished automatically as a part of the start up operation and also if, during operation, the velocity V. of the ink droplets (26), as sensed by a sensor (41), drops below a preselected reference value Vr.

Abstract: In a method of production of a cladding tube for a nuclear fuel element, an outer hollow billet (1) of a zirconium alloy and an inner hollow billet (2) of zirconium are joined by expansion of the inner billet (2). To improve the bonding of the inner and outer billets and provide better thickness control, a resilient member (4) is inserted in the inner hollow billet (2) and a pressure oriented axially of the two hollow billets is applied to the resilient member to pressure bond the outer wall surface of the inner billet (2) to the inner wall surface of the outer billet (1), and the interfaces of the opposite ends of the two billets are then joined and sealed. The integral hollow billet so formed is subjected to hot extrusion, cold working and heat treatment to produce a composite tube of reduced diameter and reduced thickness, and the inner and outer wall surfaces of the composite tube are polished.

Abstract: The fuel injector (10) includes an electronically operated control valve (60) disposed between a supply passage and a timing chamber (80) to control the admission of fuel into and out of the timing chamber. A primary piston (62) and a secondary floating piston (72) are axially spaced within the central bore (70) of the injection body, and a normally closed injection nozzle (14) is situated at one end of the injector body. A mechanical linkage (30) associated with the camshaft of the engine drives the primary pumping piston (62) against the bias of a main spring (18). The timing chamber (80) is defined between the pistons (62, 72) and a metering chamber (82) is defined between the secondary piston (72) and the nozzle (14). 
     An electronic control unit delivers a signal to the control valve (60) to close the valve and seal the timing chamber for a controlled period of time to form a hydraulic link so that the pistons (62, 72) move in concert during the injection and metering phases of the cycle of operation. When the signal from the ECU is terminated, the control valve opens, and breaks the link so that the primary piston (62) moves independently of the secondary piston (72). 
     The timing function is adjusted by the ECU relative to any preselected position of the crankshaft. The metering function is controlled by the pressure drop across a restricting orifice (98) in the passageway feeding fuel to the metering chamber (82).

Abstract: Appts. for sprinkling a liq. onto the packing of a cylindrical packed column for use in heat exchange and mass transfer between a gas and a liq. consists of feed pipes and distributer pipes arranged in the column cross-section as follows. In the three largest possible imaginary diamond-shaped zones which can be inscribed in the circle of the column, and which therefore constitute the inscribed regular hexagon, there is one feed pipe parallel to one pair of sides of the diamond leading into a set of parallel distributer pipes parallel to the other two sides. The longitudinal axes of all the distributer pipes may be above or below, or at the same level as, the longitudinal axes of the feed pipes. In a variant, in each imaginary diamond-shaped zone there may be two or more parallel feed pipes. Arrangement provides a uniform distribution of the sprinkled liq. across the packing of the column.
